Description

Technical Field

[0001] The present invention relates to the field of multimedia display technology, and more specifically, to a method for automatically typesetting and displaying vertical screen multimedia materials. Background Art

[0002] Smartphones have become an important device in people's daily work and life. Smartphone users obtain a large amount of multimedia information from their smartphones every day, including videos, audios, images, texts, etc. These multimedia materials are all typeset and processed by the mobile client platform before being displayed on the smartphone's mobile client platform.

[0003] In actual applications, the sizes of multimedia materials produced vary due to differences in the sources and specifications of the devices used to generate them. As the application of multimedia materials expands, there is an increasing need to use the Internet of Things and artificial intelligence to replace manual labor to automatically publish multimedia materials. This type of publishing is an intelligent publishing of multimedia materials based on computer software algorithms, and inevitably there will be mixed layouts of multimedia materials of different specifications.

[0004] Regarding the mixed layout of video and image thumbnails (or previews), there is a scenario where multiple multimedia materials are mixed when the number of vertical multimedia materials is an odd number. However, on existing mobile client platforms, for the sake of layout convenience, multimedia materials such as videos and images of different sizes are basically laid out using the same material template. Common examples include all multimedia materials being laid out based on a horizontal template, all multimedia materials being laid out side by side using a fixed-size vertical template divided in half, or all multimedia materials being laid out side by side using a fixed-width, variable-height vertical template.

[0005] For example, the typesetting methods in the above categories all use a unified material template for typesetting, which makes all multimedia materials appear to be neatly arranged visually. However, this type of typesetting method still has obvious defects, as shown below.

[0006] 1. All multimedia materials are laid out based on the horizontal screen template.

[0007] Since there is only one horizontal screen template, all multimedia materials are forcibly placed within the horizontal screen template for layout. Usually in this case, the vertical screen material will be scaled proportionally based on the height of the horizontal screen template to adapt to the horizontal screen template. This will cause the display screen of the vertical screen material to be greatly reduced, affecting the viewing experience. If the display terminal device is a small LED display, the displayed content may not be visible. On the other hand, even if the display terminal screen is large enough to clearly see the display content of the vertical screen material, the left and right sides of the vertical screen material are blank, and the viewing experience is poor.

[0008] 2. All multimedia materials are laid out based on the vertical screen template.

[0009] Because there's only one vertical template, all multimedia assets are forcibly placed within it for layout. Consequently, horizontal assets are scaled proportionally to the width of the vertical template to fit within it. This significantly compresses the horizontal assets, potentially occupying only one-third to one-half of the vertical assets, or even less, impacting the viewing experience. If the display terminal device is a small LED screen, the content may be indistinguishable. On the other hand, even if the display terminal screen is large enough to clearly see the horizontal assets, the upper and lower sides of the horizontal assets are blank, resulting in a poor viewing experience.

[0010] In addition, the above layout methods do not take into account the existence of square screen materials, and are usually directly classified as vertical screen materials or horizontal screen materials. The display effect is the same as the above, and there are many defects in the viewing experience. Summary of the Invention

[0011] In order to overcome the deficiency of existing multimedia material mixed layout that only adopts a single template, the present invention provides an automatic layout and display method for vertical screen multimedia materials. Through the preset processing algorithm of the client platform, all received multimedia materials are judged and run according to the processing algorithm, wherein the layout of the vertical screen template is specially considered. According to the type and quantity of the received multimedia materials, the display mode of the vertical screen material is determined, and by filling the preset materials, large blank spaces are avoided in the display page, thereby improving the viewing experience.

[0012] The technical solution of the present invention is as follows:

[0013] A method for automatically displaying vertical screen multimedia materials, wherein a client platform processes received multimedia materials including:

[0014] Step S1. Obtaining pixel ratios of the multimedia material, and classifying the multimedia material according to the pixel ratios of the multimedia material;

[0015] Step S2. According to the classification result, the multimedia material is assigned to the corresponding material template;

[0016] Step S3. Different layout processing rules are used according to the different templates to which the multimedia material belongs. If the multimedia material belongs to the horizontal screen template or the square screen template, the layout is directly accumulated; if the multimedia material belongs to the vertical screen template, the process proceeds to step S4;

[0017] Step S4. Determine the type of adjacent multimedia materials.

[0018] When the adjacent multimedia material is a horizontal screen material or a square screen material, the multimedia material and the specific material are arranged in parallel and divided into two equal parts;

[0019] When the adjacent multimedia material is a vertical screen material, proceed to step S5;

[0020] Step S5. When the number of adjacent vertical screen materials is an odd number, the multimedia materials are directly accumulated and laid out;

[0021] When the number of adjacent vertical screen materials is an even number, the multimedia material and the specific material are arranged side by side in equal parts.

[0022] The aforementioned method for automatically layout and displaying a vertical screen multimedia material, wherein the horizontal screen material is a multimedia material having a pixel ratio greater than or equal to 1.25, the horizontal screen material is displayed within the horizontal screen template, and the pixel ratio of the width to the height of the horizontal screen template is 2;

[0023] The vertical screen material is a multimedia material with a pixel ratio less than or equal to 0.8, the vertical screen material is displayed in the vertical screen template, and the pixel ratio of the width to the height of the vertical screen template is 1 / 2;

[0024] The square screen material is a multimedia material with a pixel ratio greater than 0.8 and a pixel ratio less than 1.25. The square screen material is displayed in the square screen template, and the side length pixel ratio of the square screen template is 1.

[0025] Furthermore, when the client platform pushes the multimedia material online to the offline display screen, the landscape material is sent to the landscape screen, and the pixel ratio of the landscape screen is equal to the pixel ratio of the landscape template;

[0026] The vertical screen material is sent to a vertical screen, and the pixel ratio of the vertical screen is equal to the pixel ratio of the vertical screen template;

[0027] The square screen material is sent to a square screen, and the pixel ratio of the square screen is equal to the pixel ratio of the square screen template.

[0028] In the above-mentioned method for automatically layout and displaying vertical screen multimedia materials, the client platform sets a preset library, and the preset library stores one or more specific materials. The specific materials are assigned a specific display order. In steps S4 and S5, the specific materials are displayed in a loop according to the specific display order.

[0029] Furthermore, the display triggering condition of the specific material is

[0030] 1. The adjacent multimedia materials are horizontal screen materials or square screen materials;

[0031] 2. The number of adjacent vertical screen materials is an even number;

[0032] Whenever the display triggering condition is triggered, the specific material is replaced according to a specific display order.

[0033] In the above-mentioned method for automatically displaying vertical screen multimedia materials, the client platform has a built-in top command, and the client platform uses the top command in the following situations:

[0034] The first scenario: the multimedia material is uploaded locally to the client platform for display, and the client platform formats the multimedia material according to the processing flow and places the multimedia material at the top of the display page of the client platform;

[0035] The second situation: the client platform sends the multimedia material to the offline display screen, the offline display screen plays the multimedia material, and the client platform re-places the multimedia material on the top of the client platform.

[0036] Furthermore, in the first case, the processing method of the client platform includes

[0037] Step T1. Determine whether the multimedia material is uploaded for the first time. If so, the client platform arranges the multimedia material according to the processing flow so that the multimedia material is placed at the top of the display page of the client platform. If not, proceed to step T2.

[0038] Step T2. Remove the original multimedia material, refresh the layout and display mode of the existing page of the client platform according to the processing flow, and proceed to step T3;

[0039] Step T3: Layout the multimedia material according to the processing flow, and place the multimedia material on the top of the display page of the client platform.

[0040] Furthermore, in the second case, the client platform sends the multimedia material to the offline display screen via a communication network, and the communication network is a WIFI network, a 4G / 5G communication network or a local area network.

[0041] Furthermore, the release methods for the second case include

[0042] 1. Intelligent publishing: The client platform automatically sends the multimedia material to the offline display screen according to the user's preset requirements;

[0043] 2. Precision publishing: The user sends the multimedia material to the specific offline display screen through the client platform;

[0044] 3. Active acceptance: The user actively downloads the specific multimedia material to the offline display screen through the client platform.

[0045] Furthermore, in the intelligent publishing, the preset requirements of the client platform include real-time geographic location and publishing time period.

[0046] When the current time is within the required publishing time period and a certain offline display screen connected to the client platform is within the required real-time geographic location range, the client platform sends the specific multimedia material to the offline display screen.

[0047] The present invention according to the above scheme has the following beneficial effects:

[0048] 1. The comprehensive classification of multimedia materials, material templates, and offline display screens, as well as their mutual correspondence, not only simplifies the user's material and advertising publishing process, but also achieves better material playback effects.

[0049] 2. Since the multimedia materials (including advertisements) of the client platform can be pushed and played between various pre-connected and matched offline display screens, the client platform can take into account both commercial advertising and personal entertainment at the same time, allowing the two to blend with each other, so that personal entertainment can be obtained from commercial advertising and advertising revenue can be obtained from personal entertainment.

[0050] 3. The top display function allows users to have multiple opportunities to display materials (or advertisements) at the top of the client platform page, thereby obtaining more display opportunities, increasing users' willingness to participate in the release of materials (or advertisements), and ultimately achieving the goal of increasing platform traffic.

[0051] 4. Publishers of multimedia materials (including advertisements) on the client platform have the right to independently determine the publishing price, which completely changes the pricing process of traditional advertising publishing. The pricing has been transformed from traditional advertising operators or offline display screen owners to a new advertising operation model in which advertising publishers independently determine the price. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0053] Figure 1 This is a flowchart of the processing of multimedia material publishing of the present invention.

[0054] Figure 2 Schematic diagram of the classification standards of multimedia materials, material templates and offline display screens of the present invention.

[0055] Figure 3 This is a schematic diagram of the classification of the top-placed multimedia materials of the present invention. DETAILED DESCRIPTION

[0056] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0057] Multimedia materials include video files, audio files, image files, text files, etc. In this application, multimedia materials are visual types, and in most cases they are video files and image files.

[0058] After receiving the multimedia material, the client platform Figure 1 As shown, the processing flow of the multimedia material is as follows.

[0059] Step S1: Obtain pixel ratios of multimedia materials, and classify the multimedia materials according to the pixel ratios of the multimedia materials.

[0060] The pixel ratio is the quotient of the horizontal width pixel value of the multimedia material divided by the vertical height pixel value of the multimedia material, that is, when pixels are used as the length unit, the width-to-length ratio of the multimedia material is the main basis used by this application to determine the type of multimedia material.

[0061] like Figure 2 As shown, in this application, the client platform classifies the uploaded multimedia materials as follows:

[0062] 1. Horizontal screen material: multimedia material with a pixel ratio greater than or equal to 1.25;

[0063] 2. Vertical screen materials: multimedia materials with a pixel ratio less than or equal to 0.8;

[0064] 3. Square screen materials: multimedia materials with a pixel ratio greater than 0.8 and less than 1.25.

[0065] According to the above classification criteria, with 0.8 and 1.25 as the classification boundaries, multimedia materials with an aspect ratio greater than or equal to 1.25 are classified as horizontal screen materials, multimedia materials with an aspect ratio less than or equal to 0.8 are classified as vertical screen materials, and multimedia materials between 0.8 and 1.25 are classified as square screen materials. The client platform classifies all received multimedia materials for subsequent processing.

[0066] As for unconventional multimedia materials, such as those in the shapes of circles, hearts, and five-pointed stars, such materials still have maximum pixel values ​​in both the horizontal and vertical directions, so the corresponding pixel ratio can still be obtained. Usually, the pixel ratio of such multimedia materials is mostly 0.8-1.25, and should be classified as square screen materials.

[0067] Step S2: According to the classification result, the multimedia material is assigned to the corresponding material template.

[0068] When displaying multimedia materials, the client platform needs to place the multimedia materials inside the material template. In this application, the types of material templates preset by the client platform are as follows:

[0069] 1. Horizontal screen template: A standard template for placing horizontal screen materials. The pixel ratio of the horizontal screen template's width to height is 2;

[0070] 2. Vertical template: A standard template for placing vertical screen materials. The pixel ratio of the vertical screen template's width to height is 1 / 2;

[0071] 3. Square screen template: A standard template used to place square screen materials. The side length pixel ratio of the square screen template is 1.

[0072] Among them, the size and resolution of the vertical screen template and the square screen template are fixed and unified, while the horizontal screen template has multiple subdivided templates under different pixel ratio conditions.

[0073] According to the above classification scheme, it is clear that horizontal screen materials correspond to horizontal screen templates, vertical screen materials correspond to vertical screen templates, and square screen materials correspond to square screen templates.

[0074] Step S3: Different layout processing rules are used according to the different material templates to which the multimedia material belongs. If the multimedia material belongs to the horizontal screen template or the square screen template, both are directly accumulated and laid out; if the multimedia material belongs to the vertical screen template, then go to step S4.

[0075] In this process, if the display mode of the client platform is the same width as the display terminal, then no matter it is a horizontal screen material, a square screen material or a vertical screen material, when the width is full, the horizontal screen material and the square screen material can basically be fully displayed on the screen, and will not affect the thumbnail display. For example, the typesetting method in this application is basically aimed at the case where the display mode of the client platform is a two-split screen. When the horizontal screen material and the square screen material are in a two-split screen, the height difference is not much. By fine-tuning common typesetting methods such as centering, the two can be relatively neatly typeset, and the visual experience is relatively good. Therefore, it is mainly necessary to consider the mixed typesetting of the vertical screen material. In this application, the newly updated multimedia material is at the top of the page. From a visual point of view, as the multimedia material is updated and displayed, the multimedia material moves downward.

[0076] Step S4. Determine the type of adjacent multimedia materials.

[0077] When the adjacent multimedia material is a horizontal screen material or a square screen material, the multimedia material to be typeset is arranged side by side with the preset specific vertical screen material and divided into two equal parts;

[0078] When the adjacent multimedia materials are vertical screen materials, it is necessary to determine the parity of the adjacent vertical screen materials and proceed to step S5.

[0079] When adjacent multimedia assets are horizontal or square, vertical assets are not suitable for direct visual alignment. Forcing the two to be laid out side by side creates a visual mismatch. Therefore, the vertical asset is moved directly to the top of the page and displayed separately, pushing the horizontal and square assets off the top. However, this display method leaves a gap at the top of the page, leaving a large blank space. To fill this gap, a pre-set, specific asset is automatically added to the vertical asset. This asset type is vertical and is placed on the vertical template, displaying it side by side with the newly updated vertical asset.

[0080] Step S5. When the number of adjacent vertical screen materials is an odd number, the multimedia materials are directly accumulated and laid out; when the number of adjacent vertical screen materials is an even number, the multimedia materials to be laid out are laid out in parallel with the preset specific vertical screen materials in equal parts.

[0081] The client platform determines the number of previously updated vertical screen materials. If the number of continuously updated vertical screen materials is an odd number, it means that the client platform display page should now display an updated vertical screen material and a vertical screen specific material in half and display them side by side. At this time, the next newly updated vertical screen material directly replaces the position of the original specific material and is displayed side by side with the previously updated vertical screen material, or the next updated vertical screen material replaces the original vertical screen material, and the original vertical screen material replaces the specific material. If the number of continuously updated vertical screen materials is an even number, the client platform display page should now display the two previously updated vertical screen materials in half and display them side by side. In this case, the newly updated vertical screen materials can be directly added together for layout, and a preset specific material is automatically filled in to fill the gap on the page.

[0082] In step S4 and step S5, the specific material is a filler material that is displayed in conjunction with the vertical screen material, and is therefore a vertical screen material. The client platform sets a preset library, which stores one or more specific materials. These specific materials are assigned a specific display order. When automatically filled in steps S4 and S5, all specific materials are displayed in a loop according to the display order. The change in display content is triggered by the start of the next automatic filling request. In this application, the specific material is automatically filled when the newly updated vertical screen material is displayed alone at the top of the page. When the next newly updated vertical screen material is displayed, the specific material in the next order is replaced.

[0083] In the client platform display page, in order to make a certain multimedia material be displayed at the top of the client platform page, the top command will be used for the multimedia material. Figure 3 As shown, in this application, there are two cases of the top command, as shown below.

[0084] 1. Locally uploaded to the client platform is displayed on top. There are two situations in which this type of display occurs on top.

[0085] (1) Multimedia materials are uploaded to the client platform for the first time.

[0086] During the local upload process, the client platform will determine whether the multimedia material exists in the original database of the client platform based on the uploaded content. After the matching (or retrieval) is completed, it is determined that the multimedia material is uploaded for the first time. The client platform will directly layout the multimedia material according to the above-mentioned layout rules, and its display position will be at the top of the pinned client platform page.

[0087] (2) The multimedia material is not uploaded to the client platform for the first time.

[0088] In this case, this multimedia material has already been displayed on the client platform, and you can find it by scrolling down. The client platform removes the multimedia material to be pinned separately, and rearranges the existing multimedia materials one by one in reverse order of the original display order according to the above-mentioned layout rules, and then considers the above-mentioned layout rules to determine the layout method of the pinned multimedia material, which is equivalent to bringing the original multimedia material back to the top of the client platform page. This method does not re-add the same multimedia material, but rearranges the existing multimedia materials. The most obvious manifestation is that in the personal account interface, there is only one pinned multimedia material, not multiple ones.

[0089] 2. Publish from the client platform and display at the top of the offline screen.

[0090] Similar to the terminal device display screen used in elevator advertisements, in this application, the connection between the client platform and the offline display screen can be realized through the communication network. The client platform sends specific multimedia materials to the corresponding offline display screen according to demand. The communication network used can be WIFI, 4G, 5G, local area network, etc. The offline display screen plays and displays the received multimedia materials. Specifically, the offline display screen can be a fixed display terminal or a mobile display terminal, such as the display screen on a bus, the display terminal on the vehicle-mounted equipment, etc., so that these mobile display terminals can also transmit real-time location information with the client platform through the communication network, and the client platform sends specific multimedia materials to the appropriate display terminal within the required location range. During the sending process, the client platform also needs to judge the type of the offline display screen. The offline display screen is classified as follows, and the multimedia material sent must be consistent with the type of the offline display screen.

[0091] (1) Horizontal screen: an offline display screen that uses the horizontal template pixel ratio as the standard;

[0092] (2) Portrait screen: an offline display screen that uses the portrait template pixel ratio as a standard;

[0093] (3) Square screen: an offline display screen that uses the square screen template pixel ratio as the standard.

[0094] In summary, the client platform, based on the real-time location information fed back by multiple pre-connected offline display screens and the requested command, sends specific multimedia material to offline display screens of the same type as the multimedia material within the requested location range. The offline display screen receives the multimedia material and automatically plays it, and the client platform automatically displays it at the top of the page, with the layout of the display page following the aforementioned layout rules.

[0095] There are three situations in which this category is pinned to the top.

[0096] (1) Intelligent publishing: The client platform automatically sends multimedia materials to offline display screens. According to the user's preset requirements on the client platform, the multimedia materials are automatically sent to offline display screens that meet the requirements. The specific requirements include the publishing time period and the geographical location of the offline display screen.

[0097] (2) Precision publishing: Users send the multimedia materials they upload to offline display screens through the client platform. This is usually done through communication networks such as 4G, 5G, and WIFI. The multimedia materials are sent to offline display screens through specific numbers.

[0098] (3) Active Acceptance: Users actively download multimedia materials from the client platform. This scenario is often seen with owners or managers of offline display screens. They accept certain specific multimedia materials, often advertising content, through the client platform, and the client platform sends the multimedia materials to the offline display screens in a targeted manner. On the client platform of this application, users can set their requirements and corresponding acceptance prices when uploading multimedia materials. The owners or managers of offline display screens that meet the requirements will accept the corresponding multimedia material display tasks according to the acceptance prices and obtain the corresponding fees and benefits.

[0099] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
